If somebody wants to do this, I think the overall design should go
* We may want to rewrite blame.c::get_ac_line() and the code in
pretty.c::pp_user_info() that parse author/committer lines by
using ident.c::split_ident_line() for better code reuse as a
preparation step before all of the below.
* We may want to lift the buffer length limit from the implementation
of mailmap.c::map_user() by using the strbuf API as a preparation
step before all of the below.
* We may also want to rethink its signature (we may want to get a
single strbuf and have the function parse out "Name <mail>"; I
didn't check the existing callers to see if that would make it
easier to use, and if it does not, this obviously shouldn't be done)
as a preparation step before all of the below.
* Introduce a new "struct string_list *mailmap" member to "struct
pretty_print_context" and "struct rev_info" (default to NULL);
* In log-tree.c::show_log(), copy opt->mailmap to ctx.mailmap;
* Update pretty.c::pp_user_info() to convert the email address on
"line" (between the beginning and "namelen") by calling
map_user() immediately after it parses time/tz out, and adjust
the remainder of the function to use it, when pp->mailmap is
* Teach log.c::cmd_log_init_finosh() about "--use-mailmap" option.
Allocate one "struct string_list" instance and use read_mailmap()
on it when the option is used, and store it in rev->mailmap.
